caption_attribution_description: English: Crooks Hollow Dam on March 14, 2010, when HCA’s measuring station at upstream Christie Conservation Area recorded 67.5 mm of rain
context_page_description: Crooks' Hollow Dam was a buttressed gravity dam, built of concrete in 1916 on Spencer Creek in Greensville, Ontario, Canada. About 100 yards upstream from the ruins of the much earlier Cockburn sawmill and dam, it replaced that dam in supplying water by pipe to Dundas for all uses. It also provided much greater flood control, and, more than the Cockburn dam, supplied a managed flow for water power users in the industries downstream. The Dundas Star commented on its completion: "... an excellent piece of work. It is now hoped there will be no further difficulty about securing an adequate water supply for many years to come." The dam was demolished in early 2013.
